melodious

I have a condenser mic that I was connecting to a art mp studio preamp to my soundcard. but there was a hiss most of the time. So I'm thinking of buying an audio interface, the toneport ux1. But the ux1 doesn't have phantom power, so I was wondering: could I connect the condenser mic to the art mp, and connect that to the ux1? would there still be a hiss as well?Also, i record with sonar home studio 4. could i still use that with the ux1?
